It’s Friday and you’ve got work to blow off, so let’s dive right into the ingredients. It starts with housemade vanilla ice cream. (So far, so good.) Added to that: rough-ground espresso that uses beans steeped in milk and cream for 30 minutes, which is three times longer than normal espresso ice cream. The effect: heightened caffeine potency.

Then things take an adult turn. They add four ounces of Jamaican rum (hence the name) and a few tablespoons of coffee liqueur. The result: a boozy, caffeine-laden treat that will cool you off, amp you up and mellow you out. Somehow all at once.

And in case you’ve recently sworn off rum-and-coffee-based desserts, they’ve also got an Irish Car Bomb ice cream (yes, it’s got Guinness, Baileys and Jameson), a strawberries and champagne ice cream and a drink with passion fruit and rum called the Fidel Castro.
